Well, i added them because the log messages said so... but the addresses
indeed differ from my previous setup (same hypervisor, but debian kernel
2.6.17): Sundance didn't need quirks or permissive and vi82xx complained
about more addresses.

==============
dom0# cat /proc/version
Linux version 2.6.18-1-xen-amd64 (Debian 2.6.18-2) (waldi@xxxxxxxxxx)
(gcc version 4.1.2 20060920 (prerelease) (Debian 4.1.1-14)) #1 SMP Fri
Sep 29 18:28:20 CEST 2006

domU# cat /proc/version
Linux version 2.6.17-2-xen-amd64 (Debian 2.6.17-9) (waldi@xxxxxxxxxx)
(gcc version 4.1.2 20060901 (prerelease) (Debian 4.1.1-13)) #1 SMP Wed
Sep 13 18:35:45 CEST 2006

dom0# dpkg -l 
ii  linux-image-2.6.17-2-xen-amd64      2.6.17-9
ii  linux-image-2.6.18-1-xen-amd64      2.6.18-2
ii  xen-hypervisor-3.0-unstable         3.0-unstable+hg11561-1
==============

I just upgraded the domU kernel to 2.6.18 and now i need all of the
following values for the onboard soundcard:
'000000c4:2:00000000'   # ??
'00000041:1:00000000'   # VIA_ACLINK_CTRL
'00000042:1:00000000'   # VIA_FUNC_ENABLE
'00000049:1:00000000'   # VIA8233_SPDIF_CTRL

But since i don't even get the soundcard working inside dom0, besides
mixer, i would drop this issue altogether. Asterisk will do fine without
a soundcard anyways.

Sundance however still works with 0x54.
